| 摘 要： | 提出了一种基于FPGA的TFT-LCD控制器设计方案,通过片外增加显示存储器SDRAM,以及用于储存多种字库和图片的FLASH芯片,片内嵌入精简指令集和图形加速引擎的方法,增强在文字和图形控制上的灵活性.在系统模块层次划分的基础上,利用Verilog硬件描述语言对各模块进行描述和设计,并在Xilinx的XC3S500E上加以实现.测试结果表明,该系统可支持分辨率最大为800×600的TFT-LCD显示屏,刷新频率达到60 Hz,并支持图文混排显示等功能.

| Abstract: | The design of the TFT-LCD controller based on FPGA was proposed.The SDRAM used as a display RAM and the FLASH used for storing various fonts and pictures were set outside of the controller.The reduced instruction set and geometric speed-up engine were designed in the controller.Based on the division of the TFT-LCD controller,Verilog HDL was utilized to describe the function and structure of each module.The design was realized by Xilinx XC3S500E. The testing result shows that it meets the requirement of the ... |
